342,000 burglaries in 2026: are home alarms worth it in the UK?
A security alarm is one of the most reliable ways to cut your risk of burglary, but only when it works alongside other protection and is properly installed. On its own, an alarm deters some opportunist offenders; paired with strong locks, lighting and timers, and backed by professional monitoring, it becomes part of a system that genuinely reduces harm. The sections below cover the evidence, the types available, accreditation, costs and the cyber-hygiene steps that keep a smart alarm safe to use.
TL;DR:
A monitored alarm connected to an accredited ARC is more likely to guarantee police response than an unmonitored system, especially in the UK.
Combining an alarm with physical security measures like locks, lighting, and timers significantly lowers burglary risk compared to relying on alarms alone.
Installation quality, proper setup, and regular maintenance are more critical to alarm effectiveness than the specific product brand or type.
Smart alarms require careful cybersecurity practices, such as changing default passwords and updating firmware, to prevent remote hacking risks.
Prioritizing physical security improvements first, then adding a monitored alarm, offers better protection and value for most households.

How effective are burglar alarms? Evidence and national statistics
Burglary in England and Wales has been falling. In the year ending September 2025, domestic burglary dropped by 20% to around 342,000 incidents, and police-recorded burglary offences (covering both residential and non-residential properties) fell 12% to 229,223, according to the Office for National Statistics. That decline reflects several factors, including changing patterns of home occupancy and policing priorities, but it sets useful context: burglary is a real and measurable risk, not a rare event, even as the overall trend improves.
Domestic burglaries recorded in England and Wales in the year to September 2025 were estimated to be in the hundreds of thousands, showing that the risk, while falling, remains widespread enough to plan around, according to the ONS crime bulletin., a reminder that the risk, while falling, remains widespread enough to plan around, according to the ONS crime bulletin.
Where alarms fit into that picture is more nuanced than a single statistic can show. Situational crime prevention research reviewed by the College of Policing found that combinations of measures, window locks, interior timers, double locks or deadbolts and exterior sensor lighting, sometimes referred to by the acronym WIDE, give a lower burglary risk than any single device used alone. Three or four of these measures together tend to offer the most balanced protection. An alarm is rarely the single factor that decides whether a property is targeted; it works best as one layer among several, which is why security professionals rarely recommend installing an alarm and stopping there.
There’s also a quality gap. Guidance from the National Protective Security Authority stresses that a home security system only delivers its benefit “when set up and used correctly.” An alarm that’s badly positioned, poorly maintained or never tested can fail at the exact moment it matters. Audible-only alarms that trigger too often lose their deterrent value because neighbours and even occupants start ignoring them, and a system with no monitoring behind it depends entirely on someone nearby noticing and acting.
The practical takeaway: an alarm helps, but the quality of installation and whether it’s monitored will do more to determine its real-world effectiveness than the fact that one exists at all. A cheap, badly fitted unit gathering dust in a cupboard protects nobody.
How burglar alarms work and the main types homeowners encounter
Before comparing products, it helps to understand the three broad categories that most domestic systems fall into. Each works differently once a sensor is triggered, and that difference matters more than most buyers realise.
Audible-only alarms sound a siren and flashing light at the property but send no signal anywhere else; they rely entirely on a neighbour or passer-by noticing and calling the police.
Monitored alarms send a signal to an Alarm Receiving Centre (ARC), where trained staff verify the alert and contact the police, keyholder or both.
Auto-dialler systems sit between the two: they call a pre-set number (often the homeowner’s mobile) when triggered, but without the verification an ARC provides.
Within any of these three categories, the sensors doing the actual detection are broadly similar: door and window contacts, motion detectors covering hallways and living spaces, glass-break sensors for ground-floor windows, and increasingly, smoke and heat sensors integrated into the same control panel. Wireless kits have become the default for most homes because they install quickly with minimal disruption to decor, though wired systems still offer marginally better resistance to signal interference and don’t need battery changes.
Visibility plays a bigger role in deterrence than many homeowners assume. An external bell box, visible sensors and clear signage all signal to a potential intruder that a property is protected, and that visual cue alone can be enough to send an opportunist elsewhere before they’ve even tested a door handle. Positioning sensors where they’re seen from the street or garden, not just where they’re technically effective, is a small decision that adds a layer of deterrence before anyone sets foot inside.
Monitored systems, police response and accreditation: what guarantees a response
Not every alarm that rings results in a police visit, and this is where the distinction between monitored and unmonitored systems becomes practically important rather than just technical. A monitored alarm connects to an ARC, which checks the signal against known patterns, sometimes calling the property or a keyholder first, before deciding whether the alert is genuine. That verification step exists specifically to cut down on false alarms, which is also what police forces require before they’ll commit to a guaranteed response.
Police attendance policy in England and Wales, set by the National Police Chiefs’ Council (NPCC), generally reserves immediate attendance for alarms confirmed through a compliant monitored system. According to Secured by Design, only alarms meeting these compliance requirements, verified through an ARC following NPCC policy, are likely to secure an immediate police response; an audible-only alarm, however loud, does not carry the same guarantee. Unmonitored alarms depend on a member of the public deciding to call 999 themselves, which advice from North Yorkshire’s Police, Fire and Crime Commissioner notes makes a fast response far less likely.
This is why accreditation matters before you sign anything:
Check the installer is registered with the National Security Inspectorate (NSI) or SSAIB, the two recognised inspectorates for UK alarm companies.
Confirm the system and installation meet BS4737, the established British Standard for professionally fitted alarm systems.
Ask whether the ARC the installer uses is itself NSI or SSAIB-accredited, since the installer’s certification alone doesn’t guarantee the monitoring centre meets the same standard.
Monitoring typically runs as an ongoing subscription on top of the installation cost, reflecting the staffing and verification work an ARC carries out around the clock. That recurring fee is the price of the compliance that actually secures a police response, which is worth weighing against the appeal of a cheaper, unmonitored unit.
Alarms inside a multi-layered security approach
An alarm answers the question “has someone broken in?” It does very little to answer the earlier question: “how hard is it to break in in the first place?” That’s the gap that physical security measures fill, and it’s why the College of Policing’s WIDE framework treats an alarm as one item on a longer list rather than the whole solution.
WIDE stands for Window locks, Interior timers (lights or radios on a timer to simulate occupancy), Double locks or deadbolts on external doors, and Exterior sensor lighting. According to the College of Policing’s situational crime prevention guidance, homes combining three or four of these measures see meaningfully lower burglary risk than homes relying on any single device, alarm included.
For most homeowners, the sensible order of priorities looks like this:
Secure doors and windows first: fit British Standard locks on external doors and key-locking mechanisms on ground-floor and accessible windows.
Add exterior lighting with motion sensors covering entry points, driveways and side access.
Use interior timers on lamps or a radio when the property is empty for extended periods.
Secure outbuildings and sheds, which are often overlooked but can hold tools that make forcing entry to the main house easier.
Install a monitored alarm as the layer that catches anything the first four don’t deter.
Pro Tip: Fit visible deterrents, a bell box, warning stickers, outdoor lighting, before worrying about which alarm brand to choose; deterrence often beats detection.
Treating the alarm as the final layer rather than the first purchase changes the whole buying decision. A household that’s already fitted decent locks and lighting gets proportionally more benefit from adding an alarm than one that skips straight to the alarm and leaves a weak side door untouched.
Costs, insurance and value: weighing fees against reduced risk
Installation costs for a professionally fitted alarm vary by property size, sensor count and whether monitoring is included, and most installers quote individually rather than publishing fixed rates. What’s consistent across the market is the cost structure: an upfront installation charge, followed by an optional ongoing monitoring subscription if the system connects to an ARC.
Expect a one-off installation fee covering the control panel, sensors and setup.
Monitored systems carry a recurring subscription to cover the ARC’s staffing and verification work.
Unmonitored or auto-dialler systems avoid the subscription but lose the compliance that secures guaranteed police attendance.
Insurers increasingly factor security measures into premiums, and a monitored, accredited alarm can work in your favour when a claim is assessed or a policy renewed. Some insurers set conditions around the type and certification of a system, particularly for higher-value contents, so it’s worth checking your policy wording before assuming an alarm alone satisfies any requirement.
Compliant, NSI or SSAIB-installed alarms are the systems most likely to be recognised by both insurers and police, which is a meaningful factor when weighing a slightly higher upfront cost against a cheaper, unaccredited alternative, according to Secured by Design.
Whether the investment makes sense depends on your specific situation. A property with high-value contents, a history of break-ins nearby, or a previous burglary justifies a more robust, monitored setup. A low-risk area with modest contents might reasonably prioritise locks and lighting first and treat a monitored alarm as a later addition rather than an immediate necessity.
How to choose, install and maintain an alarm
Getting a reliable system installed is less about the brand on the box and more about who fits it and how it’s maintained afterwards.
Ask for NSI or SSAIB certification before booking anyone, and check the installer appears on the relevant register rather than taking their word for it.
Get three independent quotes, a step recommended in council security guidance, to compare not just price but what’s actually included in installation and monitoring.
Avoid cold-call or doorstep sellers entirely; reputable installers don’t rely on unsolicited visits to win business.
Request a written quote and maintenance terms covering what happens if a sensor fails or the system needs servicing.
Check for Secured by Design guidance compliance, which gives a useful independent benchmark for installation quality.
Pro Tip: Keep a simple log of test dates, battery changes and any false alarms, since a pattern of false triggers is usually the first sign a sensor needs replacing or repositioning.
Once installed, a system needs routine attention to stay effective. Test sensors monthly, replace batteries on the schedule your installer recommends rather than waiting for a low-battery warning, and keep firmware updated on any connected control panel. False alarms are worth tracking seriously: beyond the inconvenience, a pattern of false triggers can affect how an ARC and, by extension, the police treat future alerts from your property.
Smart alarms and cyber safety: securing app-connected systems
A smart alarm that connects to an app brings real convenience, remote arming, live notifications, video verification, but it also opens a new category of risk that a traditional wired system never had: someone gaining unauthorised remote access to your security system itself.
According to NCSC guidance on smart security devices, the most common cyber risk isn’t a flaw in the hardware but poor configuration, default passwords left unchanged, two-step verification never switched on, firmware left out of date. These are all fixable in minutes, and fixing them closes off the paths most remote attackers actually use.
Practical steps worth taking on any connected alarm, camera or smart lock:
Change every default password immediately after setup, using a unique password rather than one reused elsewhere.
Enable two-step verification wherever the manufacturer offers it.
Keep firmware updated, ideally with automatic updates switched on.
Put smart security devices on a separate guest Wi-Fi network rather than the same network as laptops and personal devices.
Check the manufacturer’s track record on issuing security updates before buying.
For households less confident navigating router settings and app permissions, a professionally configured system reduces the chance of a basic setup mistake going unnoticed, since an installer who does this daily is less likely to leave a default password in place than someone setting it up for the first time.
Installer perspective: what professional installation brings
A professional installation typically starts with a site survey: walking the property to identify entry points, blind spots and where sensors will cover the most ground without generating constant false triggers from pets or passing traffic. That survey informs sensor placement, control panel positioning and, where monitoring is chosen, the correct setup of the connection to an ARC.
This is also where compliance gets built in rather than bolted on afterwards. An accredited installer configures the system to meet NPCC requirements from the outset, which is what ultimately determines whether a triggered alarm results in a guaranteed police response or simply a loud noise. Testing the full chain, sensor to panel to ARC, before handover catches configuration errors that a self-install might miss entirely.
We supply, configure and install Ajax alarm and CCTV systems across Guildford, Surrey and surrounding areas, covering the survey, installation and testing stages that compliance depends on. Alongside burglar alarms, our work extends into physical security and CCTV for households wanting camera coverage as part of the same layered setup.
Weighing alarms against other home-safety priorities
The conventional advice to “just get an alarm” understates how much the surrounding decisions matter. An alarm fitted to a house with a weak side door or no exterior lighting is solving the wrong problem first. My view: budget allowing, prioritise an accredited, monitored system over a cheaper audible-only box, but only after the locks, lighting and timers are already sorted. Sequence matters as much as spend.

FAQ
Do I really need a home alarm system?
Most homeowners benefit from one, but an alarm works best alongside secure locks, lighting and timers rather than as a standalone fix. Evidence from the College of Policing shows combinations of security measures reduce burglary risk more than any single device.
Do burglars avoid homes with alarms?
Visible alarms, bell boxes and signage act as a deterrent to opportunist offenders, who typically look for the easiest available target. Secured by Design notes that effective, visible systems put off burglars, though a poorly maintained or unmonitored alarm offers far weaker deterrence.
Is it worth getting a house alarm?
It depends on your contents value, local burglary risk and whether you want insurance recognition, but a monitored, accredited alarm generally offers the clearest value. NPSA guidance stresses that a correctly installed and used system provides genuine protection, while a badly fitted one does not.
What security system do burglars hate most?
Burglars tend to avoid homes with multiple visible layers of security rather than any single product: strong locks, exterior lighting and a monitored alarm together. Research referenced by the College of Policing shows three or four combined measures offer the strongest deterrent effect.
